They (Glocks) are good, but not indestructible. I've fired several thousands of rounds through each of mine, bought used. I've broken the trigger return springs in both, at Gunsite courses both times. The second time I had the other G22, as the gun jams after a few more rounds.
My father's a fairly gifted surgeon, but maintenance and mechanical objects aren't his strong point... we have to trick him into getting the oil changed in his car. He bought a first-gen Glock 19 back in... 1992 or so? It was his full-time carry gun for about 12 years, living either inside his waistband in a $12 Uncle Mike's holster or in the grungy knapsack he carried everywhere, and I've lost track of how many times we went to the range and put a few hundred rounds through it in an afternoon. The finish has worn off on the edges and corners, and the tips of the stippling on the grip are nearly river-rock smooth.
In 2004, after 12 years of use and abuse, it started jamming on him occasionally and he moved on to a new gun, having decided he was feeling "traditional" and wanted a .45. I was curious as to what had finally caused it to fail, and after dinner at his house one night he handed it to me to examine. I pulled down the disassembly lever, crept back the slide the half-inch or so that it takes to unlock it, and field-stripped the weapon down into its 4 major pieces (which takes about 10 seconds). He looked over at me in shock and said "how did you do that?"
The inside of the action was layered with a decade's worth of dust, grit, ancient sandwich crumbs, lint, brass spall, burnt powder, and other archaeological detritus that required most of an hour with solvent, a toothpick, and a wire brush to remove. It turned out that he'd never gotten around to learning to strip the weapon (
in TWELVE YEARS of carrying it), and would just swab out the barrel, then give the rear-underside of the slide a shot of a solvent/lube combo and rack it a few times before reloading after a trip to the range.
In 2005, I bought a third-gen Glock 23. It's had a few thousand rounds through it so far without a failure. It's a lot cleaner than that old Glock 19, but I'm pretty sure it doesn't have to be.
